Bearing (navigation)
"Bearing" is a term used in navigation to refer, depending on the context, to either (A) the direction of motion, or, (B) the direction of a distant object relative to the current course (or the "change" in course that would be needed to get to that distant object), or (C), the degrees away from North of a distant point relative to the current point.
In navigation, absolute bearing refers to the angle between the magnetic North (magnetic bearing) or true North (true bearing) and an object. For example, an object to the East would have an absolute bearing of 90 degrees. Relative bearing refers to the angle between the craft's forward direction, and the location of another object. For example, an object relative bearing of 0 degrees would be dead ahead; an object relative bearing 180 degrees would be behind.〔Rutstrum, Carl, ''The Wilderness Route Finder'', University of Minnesota Press (2000), ISBN 0-8166-3661-3, p. 194〕 Bearings can be measured in mils or degrees.
